Proper packaging prevents damage. All freight should be protected with proper packaging.
Proper Stacking
Stack cartons squarely on a skid with no overhang. Box flaps and corrugations should face up. Make the top surface as flat as possible. Secure cartons to the skid with banding, stretch-wrap or breakaway adhesive.
Improper stacking may lead to damage.
- Different-size containers may not  be uniform enough to have unit strength
- Damage can occur if cartons overhang a pallet because there is  no support for the freight in transit.
-  Damage can occur when a pallet doesn’t have a flat top surface. Place single containers on an outside corner or ship them loose.
How stacking strength is lost
Stacking strength is lost when pallets are improperly loaded:
- Pallet overhang loses up to 32 percent of carton strength.
- Interlocked pattern loses up to 50 percent of carton strength.
- Misalignment loses up to 30 percent of carton strength.
